Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, handpiece Water Chilling Units natural cooling source heat pipe-type cold accumulation system of the present utility model, mainly comprise: cold-storage heat-exchanger and the condensation heat pipe array being placed in external environment, described cold-storage heat-exchanger comprises the evaporation heat pipe array storing and have the airtight water tank of refrigerant He be located at airtight water tank inside, import and the outlet of described airtight water tank are connected in parallel by the cold water pipes of pipeline and handpiece Water Chilling Units, and by being located at being incorporated to of Valve controlling cold-storage heat-exchanger on pipeline, water tank is also connected with refrigerant surge tank and cushions refrigerant freezing and expansion simultaneously.Evaporation heat pipe array in described airtight water tank is as the evaporator section of heat pipe, and the steam (vapor) outlet at top is communicated with the condensation heat pipe array of external environment by evaporation tube; Described condensation heat pipe array is as the condensation segment of heat pipe, and bottom is connected to form circulation with evaporation heat pipe array again by liquid back pipe, described condensation heat pipe array is also furnished with spray washing and air-cooler cools, and refrigerated medium pump is set on liquid back pipe (due to some place demand, condensation heat pipe array is distant, working fluid condenses liquid reflux, now by refrigerated medium pump by worker quality liquid forced refluence); Described evaporation heat pipe array and condensation heat pipe array vertically rearrange by multiple row spiral heat pipe, and two helical form heat pipes that often row spiral heat pipe is 3 ~ 8cm by internal diameter are entwined, and the inwall of spiral heat pipe is provided with wick layer.The stroke of helix tube is longer relative to straight tube, has larger heat exchange area and working medium capacity, especially when two-tube helically coiling arrange time, larger heat exchange area can be exchanged for less space.
Preferably, deliver to the manifold trunk of condensation heat pipe array after evaporation heat pipe array collects working substance steam by manifold trunk, described working medium generally adopts freon.
In such scheme, refrigerant directly can adopt water, or adopts the calcium chloride water that latent heat is large.Preferably, the aqueous solution of 20% ~ 40% Disodium sulfate decahydrate and 15% ~ 25% sodium acetate trihydrate can also be contained, or contain the aqueous solution of 20% ~ 40% Disodium sulfate decahydrate and 15% ~ 30% calcium chloride, because the icing phase transition temperature of above-mentioned mixing refrigerant can reach 5 ~ 25 DEG C, thus effectively can utilize ambient temperature in the summer that temperature is higher by its latent heat of phase change, the spray washing cold wind function outside especially supporting condensation heat pipe effectively utilizes Environmental cold source.
Preferably, the outer wall at 1/2 ~ 2/3 position of the upper end of evaporation heat pipe array is smooth, and the outer wall at residue position is provided with ring fin.The spiral heat pipe adopting two strands to be wound around due to heat pipe in the utility model also to immerse in refrigerant heat absorption working medium is evaporated, and pipe range is at about 1m, evaporation endothermic Duan Guan top in this process, therefore first heat pipe outer wall freezes from middle and upper part, only the icing rate that ring fin is conducive to hypomere is set at hypomere and catches up with upper position, thus reach and evenly freeze.In addition, the more important thing is and make to keep more Large space between two of middle epimere strands of heat pipes, be beneficial to heat transfer.Further, the spacing of evaporating each heat pipe in heat pipe array and condensation heat pipe array is 8 ~ 30cm, preferred 15cm, thus under the prerequisite ensureing certain refrigeration density, prevents water tank completely icing.
Further, described spiral heat pipe adopts copper pipe, and the wick layer on inwall is porous foam layers of copper, has micropore capillarity and to be refluxed by working fluid condenses liquid absorptive collection efficiently evaporation endothermic again.Sodium chloride and electrolytic copper powder can be sintered under a shielding gas during production and form mesh-structured fine-celled foam layers of copper, be conducive to the backflow of condensed water.In addition, the junction of the cold water pipes of described airtight water tank and handpiece Water Chilling Units is provided with triple valve, thus can control cold accumulation system and whether access handpiece Water Chilling Units, also can access simultaneously.
While data center's refrigeration system normally works, the condensation heat pipe array of heat pipe is by spray washing evaporation and the heat exchange of blower fan cold wind, constantly the freon steam of evaporation heat pipe array evaporation release is carried out being cooled to liquid working substance, and be back to evaporation heat pipe array by gravitational difference effect, and the heat of vaporization again absorbed in water tank refrigerant, thus constantly from external environment condition, obtain low-temperature receiver and to the refrigerant cooling in water tank, and be cooled to mixture of ice and water or other liquid-solid mixtures gradually.When power-off occurs in data center, UPS starts drive blower fan and circulating pump, and by-pass valve control makes the low-temperature receiver of handpiece Water Chilling Units switch, for data center continues cooling.
